Why Contractors Need Public Liability Insurance

Contractors often work at client premises, construction sites, commercial properties or public areas. If you accidentally injure a member of the public or damage property during your work, you could face significant financial claims. Many clients require proof of public liability insurance before contractors can start work, especially for larger organisations or those operating under IR35 compliance rules.

How Contractors Should Check Public Liability Limits

Contractors should compare public liability limits against the contracts and sites they actually work on. A smaller domestic job may ask for a lower limit, while councils, commercial landlords, principal contractors, facilities managers and larger construction sites may request higher evidence before work starts.

The certificate should also match the insured name, trade description, policy dates and activity being carried out. A contractor working at height, using heat, employing labour or using subcontractors should check that the policy wording supports those activities rather than relying only on the headline liability limit.


Information To Prepare

  • Trade, site type and turnover
  • Required public liability limit
  • Labour, employees and subcontractors
  • Height, heat, excavation or hazardous work

Certificate Checks

  • Correct business name and policy period
  • Trade description matches the work
  • Limit meets the contract requirement
  • Exclusions and conditions are understood

FREQUENTLY ASKED QUESTIONS

How much public liability cover do I need?

Most contractors choose between £1m and £5m, but some commercial clients require £10m+. We can advise based on your contracts.
